What to do if my Mitsubishi HC3 Projector displays 'NO SIGNAL'?
- HherringtimothyJul 31, 2025
If your Mitsubishi Projector is displaying "NO SIGNAL", try these steps: * Ensure the connected device is powered on and functioning correctly. * Verify that the external device is outputting signals, especially if it's a notebook computer. * Check that the cable connecting the projector to the external device is not defective. * Confirm that the projector is connected to the external device using the correct terminals. * Make sure the connected device is correctly selected as the input source. * If using an extension cord, replace it with the supplied cable to see if that resolves the issue. If it does, use an RGB signal amplifier with the extension cord.
